I got the car home last evening and just had a few minutes to troubleshoot. I had no 12v at the starter control circuit pin. So I moved to the x42-2 connector to the right of the steering column under the dash. When I hit the start position of the switch there was no power at pin 3. I assume this tells me the switch has gone bad. Been a whole lot of starting of this car during repair so it kind of makes sense.

My question now is do I need any special tools to get the old switch out of the dash or is it pretty straightforward? Anybody had to change one of them?
